Brief communication: Unabated wastage of the Juneau and Stikine icefields (southeast Alaska) in the early 21st century [PDF]
The Cryosphere, 2018 The large Juneau and Stikine icefields (Alaska) lost mass rapidly in the second part of the 20th century. Laser altimetry, gravimetry and field measurements suggest continuing mass loss in the early 21st century.

ICESat-2 for Coastal MSS Determination—Evaluation in the Norwegian Coastal Zone
Remote Sensing, 2023 Radar satellite altimeters enable the determination of the mean sea surface to centimeter accuracy, which can be degraded in coastal areas because of the lack of valid altimetry observations due to land contamination and the altimeter footprint size.

Laser altimetry sampling strategies over sea ice [PDF]
Annals of Glaciology, 2011 AbstractWith the conclusion of the science phase of the Ice, Cloud and land Elevation Satellite (ICESat) mission in late 2009, and the planned launch of ICESat-2 in late 2015, NASA has recently established the IceBridge program to provide continuity between missions.

EVALUATION OF ASTER GDEM V3 USING ICESAT LASER ALTIMETRY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Abstract. We have used a set of Ground Control Points (GCPs) derived from altimetry measurements from the Ice, Cloud and land Elevation Satellite (ICESat) to evaluate the quality of the 30 m posting ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) Global Digital Elevation Model (GDEM) V3 elevation products produced by NASA/METI ...

Laser altimetry measurements from aircraft and spacecraft [PDF]
Proceedings of the IEEE, 1989 The techniques involved in the design and application of laser altimeter instruments are reviewed, including a description of the instrument subsystems required for the range and waveform measurements. Laser pulse transmitters based on the relatively novel technology of diode-pumped solid-state lasers are considered.
